Coin Battery Replacement - WatchMon Supervisor

The coin battery is responsible to keep the correct real time clock which we use for logging timestamps and other events into the WatchMon's onboard storage.

The coin battery is only used when disconnected from any power source (USB or 8-65v DC). The real time clock consumption will last 13 years.

However consider replacing the coin battery every few years to match its shelf life. There are some long life batteries available that will last over 10 years.

Battery model: CR 1220

Here are a few videos showing how to replace the coin battery:
